Material nonlinearity affects the stiffness and consequently distribution of internal forces moments in indeterminate structures. This has a direct impact on their behaviour design, particularly case stainless steel, where material initiates at relatively low stress levels. A method for accounting influence steel frames, including making due allowance resulting amplified second order effects, i...

Fe-Mn-Al-C lightweight steels have been investigated intensely in the last a few years. There are basically four types of steels, ferritic, ferrite-based duplex/triplex (ferrite + austenite, ferrite austenite martensite), austenite-based duplex austenite), and single-austenitic. Among these generally exhibit high strength, good ductility, outstanding weight reduction effects. Due to addition Al...

This paper presents a numerical study on structural behaviour of cold-formed stainless steel channels with circular web holes, under interior-one-flange loading case. The material properties types EN 1.4509 (Ferritic), 1.4462 (Duplex) and 1.4301 (Austenitic) were taken from the literature. In order to influence hole size, location load-bearing length crippling strength such sections, parametric...

As an analogy to nickel-based superalloys, ferritic superalloys based on Fe-Al-Cr-Ni-Ti are proposed for high-temperature applications, especially for fossil-energy power systems. Integrated computational tools will be employed to investigate thermodynamic, kinetic, and meso-scale properties of the proposed alloy systems. Meanwhile, selected microstructural attributes in representative model fe...

To avoid the toxic effect of released nickel ions and compounds from conventional stainless steels, nickel-free austenitic stainless steels have been developed. We previously established a new manufacturing process to produce nickel-free austenitic stainless steel that involves nitrogen adsorption treatment. Although the cytocompatibility of nickelfree austenitic stainless steel produced using ...

Concentrating solar power (CSP) and thermal energy storage (TES) based on molten salts still lacks economic feasibility, with the material investment costs being a major drawback. Ferritic stainless steels are comparatively cheap class of materials that could significantly contribute to cost reductions. The addition aluminum ferritic steel can result in self-passivation by forming compact Al2O3...

A ferrite–austenite 12CrNi2 alloy steel additively manufactured by laser melting deposition (LMD) was heat treated direct quenching (DQ) and tempering inter-critical (TIQ) at 800 °C for enhancing its strength–ductility balance. Both heat-treated steels have the martensite–ferrite dual-phase (DP) microstructures. The volume fractions of martensite in two are nearly similar (~ 85 vol%), while siz...

The aim of the present review is to summarize recent achievements in development ultrafine-grained austenitic/ferritic stainless steels processed by large strain deformation. Various aspects microstructure evolution and its effect on properties are considered. paper starts from an overview various methods deformation that successfully used for producing metallic materials. Then, structural mech...
